The Man With No Name

Floors – Leveling (Buildup)

Day One is complete! They removed the top layer of subfloor from the main area of the rise, sanded the lower layer a tad so that the top of the hump was at a point level with the surrounding areas of the floor, and then filled in the surrounding valley with “Fix-All”, a leveling compound.
The rectangular area filled in with Fix-All. It’s drying now, and they’ll sand it smooth tomorrow.

Another angle. There’s wood underneath it so the nails will just go straight through it when they’re nailing down the 3/4″ wood.
